BDisc Brake Banjo Bolt Washer source
 

I'm having trouble getting my banjo bolt joint to seal. Seems it's a common problem due to replacement copper washers are harder than the originals. I first tried to seal mine with the original washers - no luck. Then bought a set of replacements with the same results. I've torqued the bolt up to 35 ft. lbs. and am afraid to go much higher (spec. is 25 ft lbs.) Anyone have a particular source they've used for softer copper washers?

I read they can be heated with a propane torch and allowed to cool to make them softer. Haven't actually tried it myself though.

Hi Jim. I’ve got a few new ones. I’ll send them to you to try out.

Cheers, Anthony.

I'm having the same issue with replacement calipers on an '80 TA. I could feel the new washers where stiffer, but never thought about being too hard to indent and seal. Might have to try the annealing process.
Thanks for the tips...:biggthumpup:

Hi Jim

I've had two sets of the ones available from HBC and they have always worked fine for me. I just installed another set on this yellow car and plan to bleed the system out real soon. I don't expect any problems with them as they have always been good for me in the past.

i had the same problem ..... i had the rubber hose on the wrong side . have a really good look at the end that has the copper washers .

hbc ???

Thanks for the link. I didn't know what hbc was. Too many acronyms now days for an old fart to keep up with...:tongue:
